Wow you are really not understanding the comment you are replying to. He's discussing the business model.
And I've responded with the reality of the business model. There's no "CPU sharing" on "my computer". It's a beefy VM in the cloud.
Well, it most likely shares the CPU with other VMs, but that depends on the cloud, and the instance. And since the browser is always open, Mighty will always run that VM, with no sharing: https://news.ycombinator.com/item?id=27063554
It's not. It's literally spinning up a VM in the cloud to run Chrome and stream a video to you

Yes, but Mighty isn't running (and will never run) on your computer.
